INSIDE DOOR PROTECTOR AND GrANGBOARD.

Application filed January 11, 1924. Serial No. 685,658.

T 0 all whom t may concern.'

Be it known that I, CHARLES E. CANNA- DAY, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Inside Door Protectors and Gangboards, of which the following is a specication. i

This invention relates to car door protectors and gang boards and has for an object -to provide a protector for the inside of doors of freight cars and the like and as an improvement upon application Serial No. 662,87 L1 filed September 15, 1923.

A further object of the invention is to provide a bail, properly hinged in the doorway of a car, with a gang board secured thereto in such manner as to move with the bail in its pivotal action and to move independently thereof under varying conditions.

A further object of the invention is to provide a bail pivotally mounted in a car door in such manner as to stand substantially vertically within the limits of the car door and to swing outwardly to substantially horizontal position in which position it is supported below the level of the car Hoor and to carry on said baila gang` board.

A further object of the invention is to provide improved means for pivoting the `bail relative to the car whereby it is limited in its oscillatory movement between subg stantially a vertical position within the lines of the car door and substantially a horizontal position below the level of the car floor extending outwardly, and an improved type of gang board carried by the bail.

With these and other objects in view, the invention comprises certain novel parts, elements, units, combinations, constructions, mechanical movements, interactions and functions as disclosed in the drawings together with mechanical and functional equivalents thereof as will be hereinafter more fully described and claimed.. Y

In the drawings: l

Figure 1 is a view of the improved device as seen mounted in the car door observed from the outside of the car, the gang board being seen in elevation raised to a position inside the car door and to protect the car door from the lading.

Figure 2 is a vertical sectional view taken on line 2 2 of Figure 1.

Figure 3 is a horizontal sectional view taken on line' 3--3 of Figures 1 and2.

Figure L1 is a horizontal sectional view through portions of the car body showing the gang board in plan and in position to operate as such gang board.

Figure 5 is a horizontal sectional view taken on line 5-5 of Figure 1.

Figure 6 is a View taken on the same plane as Figure 5 but showing the position of the gang board dropped down when it is removed from the supporting structure and out of danger position.

Figure 7 is an enlarged perspective view of the block employed for pivoting the bail.

Like characters of reference indicate corresponding parts throughout the several views.

The improved door protector and gang board which forms the subject matter of this application is adapted to be associated with railway cars of the type ordinarily known Vas freight cars and represented broadly in the drawings by the parts indicatedA as vA.l The car is assumed to be equipped with a door of the usual and ordinary type represented in the drawings as the sliding door B. Within the door way and adjacent to the side posts of such door way blocks C are employed, preferably by being set into and approximatelyflush with the floor D of the car.

These blocks C are the means by which the device is secured-to the car. The device lcomprises a bail 10 having a substantially horizontal section with arms 11 turned substantially at right angles to the middle portion and providedwith trunnions 12 at the fends.

These trunnions 12 are adapted to slide `into the block C in undercuts 13 of the grooves 14C and move backwardly in said groove until the bail is raised to substan tially a vertical position against the shoulder 15, limiting said groove. To maintain Ithe bail in. such pivoted position, a bolt 16, lat each end, is inserted into and through however, is not -novel in the present'appli'- tained in rigid association with the carA structure. Preferably also an auxiliary.` bolt 18 will be employed inserted through the hole 19 in the block, although such bolt performs no function other than augmentino' the rigidity of mounting of the block C.

l'pon this bail 10 thegang board is vmounted. The gang board preferably comprises a sheet 20 of rigid material, such, for instance, as a plate of steel with cleats 21 secured rigidly to the under side of the 'plate and preterably in the term ot' angle iron, one web of each of which has a slot 22 through which the bail 10 is inserted. lThese slots 22 permit a considerable amount of adjustment of the plate Vupon the bail, such, for instance, as indicated at Figures Lland 5 whereby the plate, when operating as a gang board, may

VVbe 'moved within the limits of the car structure or moved outwardly a considerable distance to be supported wholly upon the bail,

depending upon the interval ofthe car Acarrying the gang'board and the structure supwhen the iiange ot the cleat 21 rests upon' the block C, the plate 2O :may actually be .exactly level with the '.ioor or bear upon the floor according to its position. l

Y Preferably, the'outer corners of the plate 2O vare cut out at 24, the purpose for which,

cation 'and is fully vdisclosed in said 'c0- pending application Serial No. 662,874.

To'maintain the .plate 2O in substantially vertical position Within the lines of the'door B, to serveas a..protector holding thc lading away from contact with said door, means is `provided for engaging the upper edge of said plate comprising channel ybars 25 piv- Y oted to the door 'trame at'26 and adapted to embrace the upper edge ot said plate '20.

Preferably, these two bars 25 interlock by forming a tongue 27 upon one which enters agroove 2,8 upon the other as indicated more particularly at Figure 1,V although it is to be understood that the invention is not specifically limited to this form of locking means.

VIt will .be noted 'especially from Figure 6 that, when the outer end of the plate 2O is withoutsupport, 'the relation of the slot 22 and 4bail 1.0 is such that the plate 20 may drop down to Ja substantially vertical :posi- This vmechanical often occurs thatthe car carrying such gang board is moved 'during its use or before it has been returnedto protecting position, or the structure supporting the outer Iend of 'the gang board, as for instance another car,

has been moved from such supporting position. If remaining in outstanding relation to the car, it causes damage and injur to property and people but, it pcrmittec to drop down to vertical position as shown at Figure 6,tl1is danger is eliminated or at least minimized.

In use during transportation, the gan board will occupy the position shown at Figures 1 and 2 held in approximately vertical position at or slightly within the lilies of the traine ot the car whereby the. lading engages 'against its `plate `and is restrained troni damaging contact with the door itself, preventing expensive and troublesome bulgingot the door and loss ot lading. When the car carrying this device reaches the position where the lading is to be transferred, the gang board is let down by raising the `chan` nel members 25 to release the upper edge of Athe gang board, it being then moved to substantially horizontal position as shown at Figures 4 and 5, the outer end being supported by a spotted car, a platform, 'a truck or the like. As shown at Figure '5, the gang board maybe moved a considerable distance laterally to Aaccommodate for difference in spacing ot the two supporting structures.

Ii now the car carrying "the device or the device supporting 'the outer end is moved, the gang board drops down at once to the position shown at Figure 6.

The gang 'board may also occupy this position in case the car carrying the same is co- `acting with the car carrying a similar` device, the device of the other carbeing employed for bridging the space between the two cars, one vof said gang boards `remaining inoperative as shown.

The car being again laden, the 'gang board is raised'to vertical position `by swinging first upon the bail, then swinging the bail therewith to substantially vertical 'position as shown at Figures 1 and 2 and locked by the swinging down over the upper edge of the chan-nel iron latches What I claim to Vbe new is:

1. A protector for car doors comprising n bail pivoted within the lines of the car door, and a plate carried by the bail adapted to swing with the bail to form a gan g board 'and to swing independently of the bail to safe position.

2. Acar door protector comprising'a bail Vhaving its lower ends pivoted *below the lines ofthe car il'oor `and bowed upwardly, a plate connected with r`the bail adapted 'to swing relative ,thereto 'and 'slide laterally and adapted to swing outwardly `with the Vbail and downwardly relative to the bail.

3. A car door protector comprising `a'bail having vdownwardly turned arms, means pivoting `the downwardly extending extremities of the below the level of the Sli ioor, said pivoting means including also means for limiting the movement of the bail at substantially vertical and horizontal positions, and a plate pivotally and slidably mounted upon said bail.

4. A car door protector comprising a bail embodying a normally substantially horizontal middle section and right angularly turned arms at the ends, trunnions carried at the extremities of the arms, blocks rigidly secured to the floor of the car and providing means for pivotal connection with said trunnions, stops for limiting` the movement of the bail substantially at vertical and horizontal positions, and a plate pivotally and slidably carried by the bail.

5. A protector for car doors comprising a bail embodying a substantially horizontal middle part and right angularly turned arms, pivotal connecting members carried at the ends of said arms, means co-acting With said pivotal members for attaching said bail to a car to provide for oscillation between substantially a vertical position and substantially a horizontal position, so positioned that in a vertical position the bail is Within the limits of the car door and in horizontal position the central part is Without the limits of the door, and a plate carried by the bail.

6. A car door protector comprising a vbail mounted to oscillate relative to the car tov formed for accommodating said arms, and

common means for securing said block in rigid position in a car and maintaining the bail in pivotal relation to the block.

8. In a car door protector, a bailfhavinv right angularly turned arms With aligned trunnions at the extremities of the arms, a block for each arm, each of said blocks providing a slot proportioned to accommodate the arm and an undercut to permit the insertion of the trunnion into the block, and a bolt inserted through the block maintaining said block in rigid engagement With the car and the trunnion in pivotal engagement with the block.

In testimony whereof, I affix my signature.
